Training on recognition
=========================

start Octave or Matlab
change directory to directory with this training by cd
launch tr4
This program recognizes orange color of ball and turn the 
image pic4.jpg to pic5.jpg 

Copy Hough_Circles.class and Hough_Circles.java into 
C:\Program Files\ImageJ\plugins\ (or similar path)

start ImageJ
open pic5.jpg
turn it to binary: Process / Binary / Make Binary
Process / Binary / Dilate
Process / Binary / Skeletonize
Plugins / Hough Cricles / ask for 1 circle from 30 to 100
and the program should caclulate center of the circle

What will happen if we do not decrease number of white points 
by skeletonization ?
